In ALL cases this is a FALSE ALARM as NONE of the Game Trainers GCW contain known malicious code! More info in the PC Games FAQ! In most cases using a No-CD or Fixed EXE will solve this problem! When this happens use the original EXE to play online, else you could find yourself banned from the game!

Always make a backup of the files that are overwritten by the File Archive, as the original files are usually required to update the game to a newer version or to play Online!.
